Mmmm - can I observe in this very High Level discussion (Residents/Adim) that it's obvious MS is an East Coast concern, when Highway 101, which I did in 1995, can be followed quite well, just try getting from Bournemouth in Dorset, UK to Salisbury in Wiltshire, and see where you end up. Oh yes - avoid the urge to get to Carlise by road :'(
Scenery is very nice but as TCS says, this a FLIGHT simulator ::)
The road system, etc, in Great Britain can be completely ignored in the Flight Sim, (it doesn't exist!..

...).
Whereas the road system, etc, in the U.S. is very accurate.
I often get my Maps out and navigate by air, using Roads, Railway lines, Rivers, and a Compass, in FS 2004.
I rarely get lost.
F....The reason why I live in England....but always Sim fly daily in the U.S (California).....
